Place the chocolate morsels in a microwave safe bowl and heat for 15 seconds. Stir. Repeat until the chocolate is completely smooth and melted. Allow to cool slightly.
Spread a dollop of peanut butter on top of the banana slices and, using a fork, dip the slices into the melted chocolate. Gently tap the fork to remove excess chocolate from the banana and place on a piece on parchment or wax paper.
Sprinkle on toppings while chocolate is still soft.
Allow to harden in the refrigerator. You can store the treats there or in the freezer.
